Print When Expression

Posted on November 27, 2012 at 2:00am

Hi all,

i am new to Jasper and would like to control the table rows with "print when expression"

There is already an expression in this field:
$V{REPORT_COUNT}.intValue() % 2 == 1 ? Boolean.TRUE : Boolean.FALSE

Now i would like to insert another choice. There is a var called "yavisieren". Its a boolean var. How do I insert it in the statement?

$V{REPORT_COUNT}.intValue() % 2 == 1 & $F{yavisieren} ? Boolean.TRUE : Boolean.FALSE (that doesn't work)

Can you help me?

"yavisieren" is a variable?  Then use $V instead $F
And replace & to &&
Result: $V{REPORT_COUNT}.intValue() % 2 == 1 && $V{yavisieren}

Hello there,

try... " ... $V{REPORT_COUNT}.intValue() % 2 == 1 && $V{yavisieren}.booleanValue()==true "

resp.: as a Field instead of a Variable $F ...
